Why clipped sound perceived like someone is pouring sand on drum's membrane? It feels like it happens on specific frequencies and not totally random. Which maybe means it can be filtered?
Can we filter clipping distortion based on its specific properties? (i'm not talking about spline interpolation but more like cut-off approach maybe)
Just wanted to clarify that I'm aware of the nature of clipping phenomena but more concerned about specifics of perception of this phenomena. So, after DFT/FFT of the clipped signal we're having those "nasty frequencies". Are they sharing any properties in common? are they located within some specific frequency range? Can we simply cut them off? Can we cut them off in specific cases, like when the spectral characteristics of clipped signal are well known and predictable?
The whole point of asking this is that i want to cleanup this record http://www.2shared.com/audio/SMuu991E/smrad.html and alike. It's MP3 and I don't have wav version. I feel like that 'sandy' noise has some predictable nature and identifiable by my ear. It's not like abstract smoothing of the signal, and it's clearly lies within some range, which i believe should be distinguishable from the useful signal. Please help if you know what i'm talking about.
That story is tricky because my record is in MP3 form, meaning that i have spectral form only. I have no way of getting original wav.
